Q

What do you confirm in trial denture visit?

A

because just because we selected and recorded (we did all this in intermaxillary records) it does not mean we got it right

  1. Occlusal Plane
  2. Vertical Dimension
  3. Facebow Registration (PRESERVATION)
  4. Centric Relation

Q

Freeway space importance in trial denture visit

A

Helps in verifying VDO

place dots again, swallow, rest, approximate this position and record the VDR and VDO should be 2/3 mm from there

Q

what happens when VDO is too much or too little in regards to the space of donders

A

increase in VDO (teeth too tall) —> increases the space of donders

decrease in VDO , decreases space and teeth too narrow or denture base is too thick – patient will have trouble swallowing and not enough room for the tongue

Q

Step by step corrections to decrease VDO with GOOD ESTHETICS AND GOOD RMP

include what areas you do not touch

problem 1a

A

not A and not C (occlusal plane)

so you need to warm and intrude areas B and D

  1. raise pin by the amount that you need to raise vertical (C+D now holding vertical)
  2. warm wax area D and close the articulator
  3. intrude area B, one side at a time

Q

what happens when D moves up when trying to decrease vertical

A

pin begins to touch and A and B may begin to overlap

if overlap? and dont want it? – intrude B until this does not happen

Q

Step by step corrections to decrease VDO (have excess) with GOOD ESTHETICS BUT RMP TOO HIGH

include what areas you do not touch

Problem 1b

A

Do the same thing but instead of intruding area D you will work with area C
*warm and intrude area B and C

  1. Check RMP and raise Pin
  2. Warm wax area C and close articulator
  3. Intrude area B one side at a time if there is overlap and you do not want this

leave area D alone

DONT TOUCH A

if overlap – will produce incisal guidance and will have to intrude area B one side at a time (so dont loose esthetics)

Q

Step by step corrections to decrease VDO with POOR ESTHETICS AND

include what areas you do not touch

problem 2

A

make all adjustments in the anterior first ( A and then B)
Then follow up with intruding C or D as needed, depending on whether RMP is OK

  1. Select the arch and select the side
  2. Warm wax and intrude area A (or B) ONE SIDE AT A TIME. – so have a reference
  3. chech posterior – check RMP and if it is not good - adjust C - if okay and D is okay you can RAISE THE PIN
  4. warm wax , close articulator, intrude C or D and lower

Q

Step by step corrections with insufficient VDO (have to increase) with POOR ESTHETICS OR PHONETICS

include what areas you do not touch
intra oral or extra oral adjustments?

problem 3

A

IN PATIENT MOUTH
Add to POSTERIOR FIRST to establish VDO then position anteriors as needed
- place wax on occlusal surfaces until at correct vertical
- if RMP is right – placing on D

  1. check RMP add wax to C or D
  2. Remove and reset area A – one side at a time
  3. check RMP, raise pin, warm wax, close articulator, intrude C or D

Q

Initial CR?
Confirmed?
Comparison?

A

Initial = taken with Auluwax without rims touching

Confirmed= INTRA-ORAL check bite with auluwax– teeth must not touch

Comparison –> made with articulator (so bring wax to articulator and make sure it locks in same as on patient intra-orally

26
Q

what can cause an incorrect CR?

A
  1. recorded CR in intermaxillary records incorrectly

could be anything really

27
Q

what if CR fits patient but not articulator?

A

have to remount because what is on the articulator is what is going to lab and when get back will not be right

so re mount so it is identical

28
Q

how to correct CR?

A

you need to remount but LOWER ONLY.

  1. take a new CR intraorally
  2. invert articulator
  3. ***key lower denture / auluwax into upper at slightly increased vertical since teeth do not touch
  4. stabalize
  5. remount
  6. auluwax removed and pin adjusted to the correct VDO
29
Q

gothic arch tracing - general

A

another method for recording or verifying CR

30
Q

theory of gothic arch tracing

A

restricts masticatory forces to a central bearing point in the mouth, creating a fulcrum of support for the mandible

records path of the central bearing point through protrusive and excursions

POINT AT WHICH THESE MOVEMENTS INTERSECT WOULD RECORD CR

31
Q

Intra-oral tracing assembly can be used on what three things? what does it do on each?

A

Wax rims - record CR

Wax-up - verify CR

denture – record CR for a clinical remount

32
Q

plate mounting technique of upper – which one usually on the top?

A

TRACING PLATE

upper is larger than lower and is selected for size of pt’s arch
*mounted slightly above the plane of occlusion at the correct height to maintian the VDO

33
Q

plate mounting technique of lower

A

this one is usually the mounting plate

this one is placed slightly BELOW plane of occlusion using green stick compound

need to use small enough one where the tongue will not interfere – a larger plate may force the tongue out of rest position and upwards which will interfere with the recording of CR

34
Q

position of the tracing stylus?

A

top part of the threaded pin that is inserted into the lower plate – it is also called the leveling screw

**it will make slight contact with the upper tracing/striking plate at PREDETERMINED VDO

  • next rehearse CR just like you would with wax recording
35
Q

felt tip ink use in gothic arch tracing

A

added to the striking plate/ aka tracing on upper to function as a recording medium

markings made by the stylus as patient goes into protrusive and lateral excursions

36
Q

what is starting point/point of origin in gothic arch tracing

A

CR – then go into lateral and protrusive movements

37
Q

tip of arrow in gothic arch?

A

CR position which is most posterior and is the origin

38
Q

when is CR confirmed with gothic tracing?

A

the tracing is repeated and if reproducible – then CR at the VDO is confirmed

39
Q

Differences between Bite registration for CR and gothic arch

A

BITE =

  1. bilateral recording
  2. @ increased VDO
  3. two contact areas
  4. use of Record bases + rims

GOTHIC ARCH:

  1. central tracing
  2. 1 contact point – central bearing
  3. @VDO therefore stay in hinge position without risk of translation
  4. U/L record bases
40
Q

clinical note of caution for bite registration vs gothic tracing

A

bite registration = risk of working at an increased VDO and more prone to go into translation (greater than 3mm) and there is an extra lab step of restoring the rims after remove the auluwax

41
Q

can cross bites be acceptable in denture occlusion? what about edge to edge?

A

yes - crossbite

no edge to edge– will result in cheek biting

42
Q

what is the major problem the majority of time with dentures at tooth try in or insertion?

A

ANTERIOR OPEN BITE BECAUSE THERE WAS A HEEL INTERFERENCE IN POSTERIOR AREA

43
Q

which sounds have no or little influence on phonetics

A

palatal like onion and velar like k G or NG

44
Q

labial sounds - check

A

B P M

45
Q

Labio dental sounds check

A

F and V

46
Q

dento alveolar sounds check

A

Th, T, S, D, N, Z

47
Q

1 reason we remake dentures?

A

2 is esthetics are not how pt. wants them

increased vertical

48
Q

main things at try in / trial denture

A

esthetics and phonetics
vdo
cr

does it LOOK the way it should?
does it WORK the way it should?
does the PATIENT like the way it looks?

49
Q

2 signatures you need at trial denture?

A

faculty and patient

50
Q

Wax up includes what?

A

FB preservation and processing

51
Q

retention is a function of?

A
  1. Patient adaption
  2. polished surface contour
  3. atmospheric pressure
  4. adhesion
  5. cohesion
52
Q

what maintains lip position?

A

a properly contoured denture flange

53
Q

what will an improper denture flange do?

A

CHANGE lip position so it will alter:

  • esthetics
  • phonectics
  • lip poisiton
54
Q

what is the shape of denture so lip is not displaced

A

the denture is concave where the philtrum is concave – following the borders

55
Q

where is wax up convex

A

at the borders and free gingival margin (at the collar)

56
Q

tissue is concave but denture is convex? what do you do to reach equilibrium?

A

the cheeks will be DISPLACED and the denture WILL MOVE

need to have the tissue be concave and the denture be concave

57
Q

the overall denture must be what to RETAIN THE DENTURE?

A

CONCAVE

58
Q

interdental papilla must be what shape? what does this allow? what happens if it is not?

A

CONVEX – and it will allow SELF-CLEANSING–and if not then probably cannot floss and food will get trapped

59
Q

what happens if you have undercutting in the tooth height of contour?

A

it would cause tongue to lift the denture

60
Q

max thickness of denture on palate?

A

2-3 mm - so it will not affect the speech or tongue movement for swallowing

61
Q

distance away from CEJ and border in wax up?

A

2-3 mm away

62
Q

facebow preservation definition

A

relates the upper denture to the condyle by preserving the facebow registration position on the articulator

so upper tooth impression PRESERVES relation of upper arch to condyles

63
Q

minimal indentation in facebow preservation will do what>

A

PREVENT LOCKING
